As the UK sufficient laws to cover revenge porn

I am going to have 5 chapters in my dissertation. chapter 1 will be lit review. chapter 2 will cover criminalisation(will compare with other jurisdictions e.g. america). chapter 3 copyright. chapter 4 privacy laws and chapter 5 conclusion.
This disertation will look at the current laws we have and decide if we need to introduce a new law to cover the revenge porn which is on the rise. There has recently been a court judgement on this.
